"This is an appalling crime and there is no justification or place for this type of attack," she said.

"The people who did this are thugs and anyone with information should pass it to the police."

Ms Hanna said the racial element to the incident was deeply worrying, following a series of high-profile attacks in recent weeks.

"Unfortunately, race crime seems to be on the rise recently," she added.

"There is a minority who seem intent on working up hatred, but it is not the view of the vast majority of people. Inward migration is positive. We should embrace diversity and welcome people in the same way that we are welcomed all over the world."

On Wednesday night a family of seven from the Travelling community were targeted in a gun attack in west Belfast.

A couple and their five daughters were in the property at the time.

They had been living there for less than a week.

It came 48 hours after three young Polish nationals were attacked by a 15-strong gang.

That incident took place on a strip of land which has been turned into a community football pitch near Lawnmount Street in south Belfast.

Anyone with information on Thursday's attack should contact police at Musgrave station on 101. Alternatively, information can be provided anonymously to independent charity Crimestoppers on 0800 555 111.
